水稻始穗期喷施叶面肥（药剂）混配组合的试验效果

Effects of Foliar Spraying Mixture of Pesticide and Fertilizer at Initial Heading Stage of Rice

在水稻始穗期选用抗早衰增产专用叶面肥“真打粮”、增产配方组合“保美乐”、植物调节剂“碧护”+叶面肥“美护磷钾”、防病增产药剂“拿敌稳”+“安泰生”等开展了混配叶面喷施保穗技术示范研究。结果表明,这些处理都具有增产、增强水稻抗病能力、提升稻米品质的作用。其中,“真打粮”处理的产投比高,在增强水稻抗性、提高结实率和千粒重等方面效果显著,增产增效明显。

A demonstration was conducted on the application of the technology of spraying special leaf fertilizers on rice at initial heading stage.The results showed that these treatments of spraying mixture of pesticide and fertilizer could improve the yield,disease resistance and grain quality of rice.The treatment of spraying“Zhendaliang”had high output-input ratio and milled rice rate,it could increase rice resistance,seed setting rate and 1000-grain weight,the yield was obviously increased.
